System and method for multi-band limiter with multiple frequency range

A method for limiting an audio signal, the method comprising:

• receiving, at a first limiter block, an incoming audio signal having a plurality of first frequencies;
• limiting the incoming audio signal with the plurality of first frequencies based on at least a first gain threshold to generate at least a first high audio output signal;
• receiving, at a second limiter block, the incoming audio signal having a plurality of second frequencies;
• limiting the incoming audio signal with the plurality of second frequencies based on at least a second gain threshold to generate at least a first low audio output signal;
• receiving, at a third limiter block, at least one of the first high audio output signal and the first low audio output signal;
• limiting the at least one of the first high audio output signal and the first low audio output signal based at least on a total gain threshold to generate a modified low audio output signal;
• and
• combining the modified low audio output signal to the first high audio output signal to generate a final output audio signal that exhibits reduced distortion during audio playback based at least on the first gain threshold, the second gain threshold, and the total gain threshold.

A computer-program product embodied in a non-transitory computer readable medium stored in memory and executable by at least one controller to limit an audio signal, the computer-program product comprising instructions for:

• receiving, at a first limiter block, an incoming audio signal having a plurality of first frequencies;
• limiting the incoming audio signal with the plurality of first frequencies based on at least a first gain threshold to generate at least a first high audio output signal;
• receiving, at a second limiter block, the incoming audio signal having a plurality of second frequencies;
• limiting the incoming audio signal with the plurality of second frequencies based on at least a second gain threshold to generate at least a first low audio output signal;
• receiving, at a third limiter block, at least one of the first high audio output signal and the first low audio output signal;
• limiting the at least one of the first high audio output signal and the first low audio output signal based at least on a total gain threshold to generate a modified low audio output signal;
• and
• combining the modified low audio output signal to the first high audio output signal to generate a final output audio signal that exhibits reduced distortion during audio playback based at least on the first gain threshold, the second gain threshold, and the total gain threshold.
